PAPERING MACHINE I Filed Sept. 12, 1938 4 Sheets-Sheet 4 ATTORNEY) Patented Feb. 4, 1941 UNITED STATES PATENT OFFICE 18 Claims.

One object of my invention is to provide a papering machine which is durable and comparatively inexpensive to manufacture and simple to operate. 1

Another object is to provide a papering machine in which the paste is applied to the wallpaper in the form of a thin film, there being a reservoir for paste, with a paste roller rotatable therein and arranged relative to a roll of paper being unrolled, so that the back of the paper passes thereover.

Another object is to provide wiper mechanism so associated with the paper and paste, or pasteapplying roller, that a film of the proper thickness of paste on the paper is insured.

Another object is to provide a traction roll around which the paper travels, and means to rotate the traction roll so as to propel the paper through the machine.

Still another object is to provide a papering machine in which a main clamp is mounted for receiving the initial end of a strip of paper from the roll of wall paper, after which, upon operation of the traction roll, the strip of paper is fed into a compartment of the machine in a corrugated formation and held against accidental pasting of the corrugations together by a series of separators.

A further object is to provide weight rods actable with the strip of paper for causing it to assume such corrugated formation within the cabinet, the separators and weight rods being automatically moved to their operative positions by operation of the traction roll.

A further object is to provide a yoke within the cabinet, having an auxiliary clamp carried thereby and adapted to coaot with the paper after it has been folded in corrugated formation Within the cabinet, the separators and weight rods being automatically moved to their operative positions by operation of the traction roll.

A further object is to provide a yoke within the cabinet, having an auxiliary clamp carried thereby and adapted to coact with the paper after it has been folded in corrugated formation in the cabinet, to retain the initial end of the next strip of paper after the first strip has been severed and is ready to be applied to the wall.

Still a further object is to provide a trimmer roll and a trimmer disc coacting therewith, whereby the edge of the paper is automatically trimmed as it is fed through the machine by the traction roll or the paper can be split thereby.

Further objects are to provide means for releasing the weight rods at proper times for coaction with the strip of paper, means to raise the weight rods and swing them to an inoperative position and means to insure that each end of each weight rod will move downwardly at the same speed, so that the weight rods are not tilted in the machine, and thus binding of the rods is avoided.

Still further objects are to provide modified constructions in which the wallpaper has applied thereto a film of paste and the paper may be merely withdrawn from the machine and thereupon applied to the wall or withdrawn onto a table.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my papering machine whereby the objects contemplated are attained, as set forth more in detail in my specification, pointed out in my claims and illustrated in the accompanying drawings, in which Fig. 1 is a vertical sectional view through my machine, the section being taken on approximately the line l-| of Fig. 4;

On the accompanying drawings, I have used the reference character C to indicate a cabinet. The cabinet C includes a front wall I 6 and a back wall I2. The wall I 6 has an openable portion Ilia (see Fig. 4) to permit access to the cabinet for inserting rolls of wallpaper I 3 therein. Within the cabinet C, I provide a trough I4 adapted to contain paste I5. The paste I5 is preferably of the consistency commonly used when brushing the paste onto the wallpaper by hand.

J ournaled for rotation in the trough I4, so that its lower portion dips into the past I5, is a paperpasting or paste-applying roll I6. The roll of paper I3 is adapted to be supported in a pair of pivoted arms II, so that the weight of the paper roll causes it to contact at all times with the pasting roll I6. t is therefore obvious that, as a strip of paper I3a is unrolled from the roll I3, a film of paste will be applied thereto by simultaneously rotating the roll I6 in the proper direction.

For unrolling the roll I3, I provide a traction roll I8. The strip of paper I3a passes over the traction roll and then over a trimmer roll I9. The rolls I6, I8 and I9 are rotated simultaneously by a belt drive comprising pulleys I6a, I8a and I8a, and a. belt 20, as shown in Fig. 5. The roll I8 is rotated by a crank I8b (see Fig. 1). The crank I8b is adapted to be rotated by hand although, obviously, other means such as an electric motor could be provided for this purpose.

To insure that too heavy a film of paste is not applied to the strip I3a, I provide wiper blades 2I and 22. These, as shownin Fig. 4, are pivot ally mounted and urged to engage the pasting roll I6 and the paper strip I 3a by springs 2 Ia and 22a. The blades 2| and 22, as illustrated in Figs. 1 and 2, are serrated, which I find effectively wipes the desired excess of paste from the roll and strip in a desirable manner.

For coaction with the trimmer roll I9 I provide one or more trimmer discs 23. These are pivotally supported on a rod 24 and urged to engage the trimmer roll I9 by springs 240.. They may be set at different distances apart so as to trim the paper to any width desired.

The cabinet C is divided into three compartments, which are shown as CI, C2 and C3, and in Figs. 1 and 2 are respectively the left-hand, center and right-hand compartments. These compartments are shown respectively in Figs. 3, 4 and 5.

The parts I4 to '24, thus far described, are located in the central compartment C2. Also located in this compartment is a yoke 25, separator rods SI, S2 and S3, weight rods WI, W2 and W3, and a main clamp 26-21. The yoke 25 is inverted U-shape, as shown in Fig. 1, with the lower ends of its arms pivoted to links 28. The links 28 are secured to a shaft 29 which extends into the compartment C3 and has thereon a lever 36.

The lever 36 is connected by a link 3I with an operating lever 32, which can. be manipulatedby the operator extending his hand through an opening 33 of the front wall l of the cabinet C. By pulling outwardly on the lower end of the lever 32, the rock shaft 29 is rotated clockwise for lowering the yoke 25 to the position desired. The yoke 25 is normally retained in the position shown in Fig. 4 by springs 34. It can be swung rearwardly (toward the rear wall I2) by the operator during the operation of the machine. During such operation, a lid 35 of the cabinet C is left in open position as shown in Figs. 3, 4 and 5.

The yoke 25 includes clamp members 36 which are preferably rubber-headed pins slidably mounted in a cross bar 31. Springs 36a are interposed between the heads of the pins 36 and the cross bar 3! to aid in the clamping action as will hereinafter be obvious. The cross bar 31 is slidable relative to brackets 38 which are secured to the yoke 25, as shown in Fig. 9, a pair of pins 39 and 40 in a slot 4I serving as the slidable connection. The cross bar 31 is normally retained in raised position by a spring 42 at each end of the bar. The bar can be lowered manually and the pins 40 swung into bayonet extensions- 43 of the slots 4| when it is desirable to cause the clamp elements 36 to engage the yoke 25.

The separator rods SI, S2 and S3 are also yoke-shaped, as shown in Fig. 1 with their lower ends secured to rock shafts 44 as shown in Fig. 5. The rock shafts 44 are extended into the compartment C3 and terminate in levers 45. The levers 45 are adapted to be actuated by links LI, L2 and L3, which are normally held against a stop bar 46 by springs 41. Each link is provided with a first shoulder 48 and a second shoulder 49. The shoulders 48 and 49 are adapted to engage the stop bar 46, the springs 41 tending to retain such engagement.

The links LI, L2 and L3 are adapted to be released by cams 50, and 52. Each cam is in alignment with its particular link, as shown in Fig. 1, and has a cam lobe to engage the upper end of the link and release the shoulder 48 from the stop bar 46 whereupon the link is pulled upwardly by its spring 41 and the second shoulder then engages the stop bar. The links LI and L2 are shown with their shoulders 49 and 48 respectively engaging the stop bar in Fig. 5.

The main clamp 26-21 consists of the bar 26 and sliding pins 21 having rubber covered heads on their lower ends. The pins 21 slide in a bar 53, which is stationarily mounted on the back wall I2 of the cabinet C (see Fig. 4). The bar 26 is supported slidably by rods 54, which slide in a stationary cleat 55 on the back wall I2. Interposed between the bar 26 and the cleat 55 are springs 26a which normally retain the clamp bar 26 raised and in engagement with the pins 21. Springs 27a on the pins 21 alsoaid in resiliently clamping the strip 23a in the main clamp 26-21.

The rods 54 extend downwardly and connect with levers 56 extending from a rock shaft 51. The rock shaft 51 extends into the compartment C3 (see Fig. 5) and terminates in a lever 58. The lever 58 is adapted to be raised by depressing a foot pedal 59 which is pivoted at 68. An opening 6| is provided in the front wall II] from which the pedal 59 projects. I

The weight rods WI, W2 and W3 are adapted to be normally supported by rod hooks 62. The rod hooks 62 are provided with individual hook elements for the weight rods and are pivoted as at 63 to levers 64. The levers 64 have stop flanges 65 to engage the rear ends of the rod hooks 62 and swing the rod hooks, together with the weight rods to the position of Fig. 7 when a rock shaft 66 on which the levers 64 are mounted is rotated clockwise. When the rock shaft is rotated counterclockwise, the rod hooks 62 are first lowered until they strike stop pins 61, as shown by solid lines in Fig. 6, and are then moved horizontally 'rearwardly to the dotted position upon further counterclockwise rotation of the rock shaft 66. The rock shaft 66 extends into the compartment C3 as shown in Fig. and terminates in a lever 68 which may be manipulated for rocking the shaft.

The weight rods WI, W2 and W3 are adapted to be released from their supported position by levers 69. In Fig. 6, the weight rod WI has already been so released by clockwise rotation of a rock shaft ID from which the lever 69 depends. For rocking the shaft III I extend it into the compartment C3 as shown in Fig. 5 and provide thereon a crank pin II. The crank pin II overlies one end of a lever I2 which is pivoted at I3. The other end of the lever I2 cooperates with a cam I4. The cam I4 is mounted on a camshaft I5, the cams 50, EI and 52 being also mounted on this shaft.

The shaft I5 is rotated automatically by rotation of the traction roll I8 by step-down gearing I6. The gearing I6 is frictionally connected to the camshaft 15 as by being interposed between a collar I60, and a friction spring 1611 (see Figure 2 The friction spring is interposed under tension between the gearing and the cam 14 on the camshaft I5.

The camshaft I5 includes a dial 1! for indicating the number of feet in the strip of paper I3a. The dial 11, together with the cams 50, 5|, 52 and I4, may be rotated relative to the gearing I6 by the operator engaging the dial and rotating it against the friction of the spring 16b. Thereafter the cams will be rotated by the gearing. The purpose of this arrangement is so that the dial II can be set with its zero point coincident with a pointer 'I'Ia (see Fig. 2), at the beginning of each strip of paper and the cams will thereafter operate in proper sequence and at the proper times during the operation of the machine.

To prevent the weight rods from wiping the paste off the strip I3, I provide spaced enlargements 'IB thereon, as shown in Fig. 2.

The weight rods are adapted to fall on the strip I3a as shown in Fig. 6 and insure that the strip will depend properly within the compartment C2 so that it can be folded in a corrugated fashion and supported by the separators SI, S2 and S3 as shown in Fig. '7. The weight rod WI is shown dotted in the lower portion of the figure merely to indicate its position prior to being raised by mechanism which I will now describe.

The raising mechanism for the weight rods consists of carriers I9 which are provided with notches to receive the weight rods. The carriers I9 are provided with hubs 19a slidable on vertical rods 19b. Means for raising the carriers is provided in the form of pins 89 extending from them through vertical slots 8| into the compartments CI and C3, as shown in Fig. 5. The pins 89 are connected to cables 82 which extend over pulleys 83 and 84 and are anchored at 85. Journal pins 86 for the pulleys 83 are stationary relative to the cabinet C while the pulleys 84 are carried by arms 81 on a rock shaft 88. The portion of the rock shaft 88 in the compartment C3 is provided with a lever 89, which can be pulled outwardly through the slot 33, thereby swinging the arms 8! and the pulleys 84 downwardly to effect raising of the pins 89 and the carriers IS. The particular arrangement of pulleys 83 and 84 and anchorage point 85 effect considerable movement of the carriers I9, with a comparatively short swing of the lever 89.

In Fig. 8, I show a modified construction which insures that the ends of the weight rods will move downwardly at the same speed. The weight rods are provided adjacent each end with pinions 99 cooperating with racks 9|; Straps'92 engage the weight rods to retain the pinions in mesh vwith the racks. I still provide the same carriers I9 for raising the weight rods, but after the rods are raised as high as the carriers will go they are swung upwardly to a position out of the way by arms 92. The arms 92 are mounted on a rock shaft 93 which has an operating lever 94 located in the compartment CI. The upper ends of the racks 9|, it will be noted, are arcuate, and a hook member 95 is provided for each weight rod. As the weight rods are swung upwardly by the arms 92, they lift the hooks and finally drop into position for holding the Weight rods whereupon the lever 94 can be returned to its inoperative position.

For releasing the weight rods progressively, I

provide a single cam 96, taking the place of the three cams 56, 5| and 52. The cam 96 is provided with progressively higher lobes 59a, 5Ia and 52a, for the purpose of raising the left hand end of a lever 91 pivoted at 98. The other end lowers a bar 99 having pins I69, I9I and I62 to engage the hooks for the weight rods WI, W2 and W3 progressively thus releasing them at different times during the rotation of the cam 96. Also, in Fig. 8, I show a modified construction for the paper pasting roll of my machine. The roll in this figure is indicated at I60, and a second roll I611 is rotatable therebelow. The rolls Ito and I6?) are rotated in opposite directions by, suitable gearing and a small roll I90 tends to cause the paste I5 to pile up as at I5a and be thus effectively transferred to the roll Ilia. In this way a relatively deep trough Ma of large capacity can be used and initially filled to the line indicated at I612 on the paste-applying roller 16a. yet paste will be effectively applied to the roll I6a even when the level of the paste is low as shown in this figure.

In Fig. 10, I show a modified construction in which a casing IIIII has contained therein a roll of paper H3 passing over a pasting roll H6. A trough II4 is provided for the paste H5 and a strip H361. of the wallpaper may be grasped by the operator I65 and pulled outwardly through a slot I96 in the casing I99. A roller I9? is provided geared to the roller H6 by gears I29. The paper extends under the roller Iil'I so that it is not dragged across the upper edge of the slot. The strip 3a can be applied directly to the Wall surface indicated at I68 and trimmed off at its lower end after the strip has been pasted on the wall. The casing I64 serves as a. convenient means for the operator I65- to stand on during the papering operation. A door I99 is provided through which access may be had to the interior of the casing I64 for placing afresh roll II3 therein.

If it is desirable to use a table such as T in Fig. I I, on which to work, an'arrangement can be provided consisting of a pasting roll 2I6,

trough 2M, and idler rolls 2I8 and 2I9 supported on the table. The rolls 2I6 and 2I8 may be geared together by gears 229 so that they rotate simultaneously at the proper relative speeds as the paper strip 2I3a is pulled over the roller-2I9 and across the top of the table T. Pivoted' arms 2I'I are provided for supporting the roll of paper 2I3. On the table T, the strip 213a may be trimmed and cut to length in the ordinary manner.

The top 35 of the cabinet C may be closed and used when desired like a table top for pasting and trimming operations.

Practical operation In the operation of my paper pasting machine, first of all the operator must have the hook rods 62 in the raised position shown in Fig. 7 and the separators SI, S2 and S3 swung forwardly as shown in Fig. 4. He then places the roll of paper 13 in position supported by the arms I! and threads the strip I3a around the traction roll [8, over the trimmer roll l9 and then into the clamp 36 of the yoke 25. The clamp is in open position as in Figs. 4 and 9 and the initial end of the strip 13a is passed therethrough to extend about an inch beyond the yoke. The clamp bar 31 is then lowered and retained in lowered position by the pins 40 engaging in the bayonet portions 43 of the slots M. In this position, the springs 36a are under compression thereby clamping the strip in position.

The yoke 25 is then lowered by pulling outwardly on the downwardly extending end of the lever 32 and is swung rearwardly by the operator engaging the yoke or bar 31, finally assuming a position approximately as shown in Fig. 7. (The separators SI, S2 and S3, however, are in the forward position as in Fig. 4.) The foot pedal 59 is then depressed for opening the main clamp 26-21 and the extending initial end of the strip i311 enters the main clamp. Thereupon the pedal 59 is released for closing the main clamp and the auxiliary clamp on the yoke 25 is opened. The yoke may then be swung forwardly to the position of Fig. 4, so that it remains out of the way until it is necessary to use it again.

The foregoing description of the operation is for preparing the machine for use. I will now describe an operating cycle of the machine.

The rod hooks 62 are swung from the position of Fig. 7 to the full line positions of Figs. 4 and 6 by swinging the lever 68 in the compartment C3 counterclockwise. The dial TI is set at zero and the operator commences to turn the crank 18b for feeding the strip 13a through the machine. Immediately the cam 14 lifts the crank pin 1i forswinging the lever 69 to the position shown in Fig. 6, thus releasing the weight rod WI from the rod hooks 62.

As the traction roll I8 is further rotated, the strip l3a will depend between the main clamp 2621 and the separators SI, S2 and S3, as shown by solid lines in this figure, and will be carried downwardly by the weight rod WI. During such downward movement, the cam 50 will cause the shoulder 48 of the link 'Llto be released as in Fig. so that the spring 41 for this link will pull the link upwardly until the shoulder 49 engages the stop bar 46. This will swing the separator 5| to the dotted position shown in Fig. 6 so that one corrugation of the strip l3a is then depending between the separator 5| and the main clamp. Thereafter during further rotation of the operating crank l8b the weight rod W2 will be released, the separator S2 will be swung rearward, the weight rod W3 will be released and the separator S3 will be swung rearward. By this time the dial Tl will register in the neighborhood of twelve feet as each loop or corrugation of the strip [3a is approximately four feet long.

If the paperhanger desires a twelve-foot piece of paper, he may now stop rotation of the crank I812. The next step is to slide the rod-hooks 62 back to the dotted position of Fig. 6, so'that the rods can be raised in front of their respective hooks thereof. The lever 89 is then pulled outwardly through the slot 33 for elevating the rodraising elements 19 whereupon they will assume positions in front of their hook elements of the rod hooks 62. While in this position, the lever 68 is rotated clockwise for first shifting the hooks of the elements 62 to the full line position of Fig. 6 and then elevating them to the position of Fig. 7 for subsequent repetition of the cycle of operation.

All three of the separators Si, S2 and S3 are then swung forwardly to the position of Fig. 7 for pasting the corrugations of the strip 13a together. This is done by pressing rearwardly on the upper ends of the links Ll, L2 and L3 so that their shoulders 49 are released from the stop bar 46 and the springs 41 then swing the separators to the desired position.

The next step is to swing the yoke 25 forwardly as in Fig. 7 to a position adjacent the point indicated by the arrow I03 and lower the clamp bar 31 so as to clamp the paper in the auxiliary clamp of the yoke. A knife can then be passed along a line indicated by the arrow I03 to sever the strip I 3a from the remainder of the roll I3. The yoke 25 may then be permitted to swing forwardly to the position of Fig. 4, where it is out of the way and the corrugated strip l3 a lifted out of the machine and applied to the Wall. The corrugated formation of the strip permits ready handling of the paper by the paperhanger during this process, as well as making it unnecessary to have the cabinet half as tall as the strip of paper is long as would be necessary if the separators and their associated mechanism were not provided.

If it is desirable to have less than twelve feet of paper, for instance ten feet, then the operator merely stops turning the crank I817 when the dial l7 registers ten feet'in which case the weight rod W3 would only be about half way down. If six feet of paper are required only the weight rods W1 and W2 are released and the weight rod W2 is only about half way down at the time of severance of the strip from the roll. Thus it is obvione that any desired length of strip can be taken from the machine and if longer strips are desired the machine can be designed to release addition- 9.1 weight rods and to include additional separators.

The yoke 25 may now beswung forwardly and downwardly again to clamp the initial end of the next strip in the main clamp. The yoke clamp i then unclamped and the yoke permitted to swing forward again to the position of Fig. 4 whereupon the cycle of operations described is repeated.

The operation of the device shown in Fig. is believed obvious. After one strip of paper is applied tothe wall, the casing I04 may be shifted along the wall and the next applied and so on. With the apparatus shown in Fig. 11, a paperhanger accustomed to working on a table top can still do so and the apparatus merely serves as a convenient automaticmeans to apply the paste to the paper without the necessity of having to brush the paste on the paper.

From the foregoing description, it is obvious that I have provided a papering machine in which the wallpaper may have properly applied thereto a film of paste and the machine manipulated so that the paper is supported in the machine in a manner which avoids all danger of the folds or corrugation becoming all pasted to-- gether and for convenience in the application of the strip to the wall after it is removed therefrom. The paper can be trimmed during the pasting operation and the paperhanger need not measure the paper, as the dial T! at all times indicates just how much paper is being fed into the strip to be removed from the machine. The mechanism is easily operated and after a few minutes instruction and practice one man can use my machine and paper a room in approximately the time that it usualy takes two men to do so where the paperhanger has a helper applying paste to the paper by the brush method.

Some changes may be made in the construction and arrangement of the parts of my apparatus without departing from the real spirit and purpose of my invention. Accordingly, it is my intention to cover by my claims such modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
